Typhoon is a kind of natural disaster that often happens in coastal cities in summer, which endangers people's life and property safety. Typhoons often carry a large amount of precipitable water vapor, precipitable water vapor distribution and dynamic change during the typhoon transit process is of great significance for the monitoring and forecast of typhoon. Compared with the traditional use of sounding balloon observation water vapor, PWV (Precipitable Water Vapor) retrieval using ground-based Global Navigation Satellite System (GNSS) has the advantages of high temporal and spatial resolution and near real time. Therefore, this paper inversed the PWV based on GNSS observation data in Guangxi, verified the reliability of GNSS inversion PWV by using the PWV observed by high-precision sounding station, and finally analyzed the dynamic changes of water vapor in Guangxi during the passing of Typhoon Mangkhut in combination with ERA5 reanalysis data. The results showed that: (1) GNSS-PWV has good consistency with the measured data of sounding station, which can be used to monitor the change of precipitable water vapor in extreme weather. (2) GNSS-PWV and ERA5 PWV can directly and clearly reflect the dynamic transport process of precipitable water vapor in time and space during typhoons, providing reference for predicting the movement, intensity and precipitation of typhoons.
